BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Petunia plant, botanically known as (Petunia×hybrida)×Calibrachoa sp. and hereinafter referred to by the name ‘Duesunpursky’.

The new Petunia plant is a product of a planned breeding program conducted by the Inventor in Encinitas, Calif. The objective of the breeding program is to create new moderately vigorous and trailing Petunia plants with numerous attractive flowers.

The new Petunia plant is a naturally-occurring whole plant mutation of a proprietary selection of (Petunia×hybrida)×Calibrachoa sp. identified as code number TT-0813, not patented. The new Petunia plant was discovered and selected by the Inventor as a single flowering plant within a population of plants of the parent selection in a controlled greenhouse environment in Encinitas, Calif. on Nov. 11, 2015.

Asexual reproduction of the new Petunia plant by terminal vegetative cuttings in a controlled greenhouse environment in Encinitas, Calif. since Nov. 12, 2015 has shown that the unique features of this new Petunia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Petunia have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Duesunpursky’. These characteristics in combination distinguish ‘Duesunpursky’ as a new and distinct Petunia plant:

-   -   1. Mounding to outwardly trailing plant habit.     -   2. Moderately vigorous growth habit.     -   3. Freely branching habit.     -   4. Early and freely flowering habit.     -   5. Medium to large-size flowers with purple-colored petals with         greyed and dark purple-colored centers and venation.     -   6. Good garden performance.

Plants of the new Petunia can be compared to plants of the parent selection. Plants of the new Petunia differ primarily from plants of the parent selection in flower color as plants of the parent selection have darker purple-colored flowers.

Plants of the new Petunia can be compared to plants of (Petunia×hybrida)×Calibrachoa sp. ‘Duesunblu’, disclosed in a U.S. Plant patent application Ser. No. 15/530,211. Plants of the new Petunia differ primarily from plants of ‘Duesunblu’ in flower color as plants of ‘Duesunblu’ have dark violet-colored flowers. In addition, plants of the new Petunia have slightly larger flowers than plants of ‘Duesunblu’.

Plants of the new Petunia can be compared to plants of Petunia×Calibrachoa ‘Dancalipet’, disclosed in U.S. Plant Pat. No. 16,063. Plants of the new Petunia and ‘Dancalipet’ differ primarily in the following characteristics:

-   -   1. Plants of the new Petunia are more trailing than and not as         mounding as plants of ‘Dancalipet’.     -   2. Plants of the new Petunia are more vigorous than plants of         ‘Dancalipet’.     -   3. Plants of the new Petunia have larger flowers than plants of         ‘Dancalipet’.     -   4. Plants of the new Petunia and ‘Dancalipet’ differ in flower         color as plants of ‘Dancalipet’ have red purple-colored flowers.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the early autumn in summer in 15-cm containers in a polyethylene-covered greenhouse in Encinitas, Calif. and under cultural practices typical of commercial Petunia production. During the production of the plants, day temperatures averaged 26° C., night temperatures averaged 17° C. and light levels averaged 4,500 lux. Plants were pinched one time at planting and were seven weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
